I always thought Pat was doing the Johnny Woods mod, not vice versa......
Roland Jakel in Hamburg was making and selling the rear adjustable a-arms and with current deflated euro exchange rates the price looks a lot more attractive. Find him through here; http://www.jaeckel-partner.de/en/detomaso.html

Johnny Woods is doing the Pat Mical modification to my front upper A-arms for 170 £ which is around $250.00 Dollars and it is supposed to be the same modification Pat Mical does (I was told he taught Johnny how to do it) . Johnny told me about friends of his in Germany that make the adjustable upper rear A-Arm ( they look just like the picture Julian posted) for $450.00 Euros which at today's conversion rate is $571.50. I will be happy to send pictures and contact info to anyone who is interested. ( I can send pictures of either the front Ala Pat Mical or the Rear similar to Julian's or both so please specify)

Julian,
I talked to Pat a while back, and he said that there is potential miss-alignment between the upper and lower rear control arms that can to some degree bind the rear suspension. I think his mods addresss the miss-alignment in addition to the camber adjustment.
Given the weight of the components and friction in the ball joint, shaft, and bushings, it may be hard to detect a bind, I'm not sure how big an an issue it actually is?

Mike,
Rarely do I disagree with you, but..... I would counter your argument as false economy, you conclude that additional length is required in the upper a-arm to improve camber, but for $369 you get a relatively fixed 3/8" with the lengthened a-arms. Add in a pair of new upper ball joints at $350 as most prudent owners would do at that point and you've just spent what the all-in adjustable (and longer) units cost and they don't require the ball joint.
I'm not talking the $1200 Pat Mical mod as discussed recently, but a simple outer heim joint a-arm of the type I have on both Pantera's like so...

IMO this offers far more rear camber flexibility especially for a low slung wide body Pantera. Furthermore Byers price requires you exchange in your current a-arms, whereas I purchased the above outright and could probably get some $$ back on my oem units.

Larry Stock, PPC Reno had a batch made up using the ones on my GT5 as patterns. These had considerably beefier heims than any the other vendors seemed to be currently offering.
I have never understood the desire to have adjustment at the upper A-arms. Given that all the alignment adjustments are made below, you don't really need *adjustable* upper A-arms, you just need *longer* upper A-arms. Longer arms will send the tops of the hub carriers out a fixed amount, and then you can tweak the alignment in the normal fashion with shims down below.
As far as I know, only Precision Proformance (and maybe Hall Pantera???) sells fixed-length extended A-arms. They are much less expensive than the adjustable versions, use the stock ball joints, and do everything you need. Very highly recommended. :>)
